Description

Example embodiments relate to electronic vaping devices, e-vaping devices, or the like, and components thereof.
E-vaping devices, also referred to herein as electronic vaping devices (EVDs) may be used by adult vapers for fluid portable vaping. An e-vaping device may include a reservoir that holds pre-vapor formulation and a vaporizer assembly that may heat pre-vapor formulation drawn from the reservoir to generate a vapor.
Some e-vaping devices are configured to enable replenishment of the pre-vapor formulation held in a reservoir of the e-vaping device (that is, refilling of the reservoir).
US 2017/071251 A1 describes a smoking device comprising a liquid evaporator comprising a liquid reservoir, a wick and a liquid-heating device. The device also comprises a tobacco heater comprising a chamber for receiving tobacco and a chamber-heating device for heating the tobacco in the chamber. A tobacco-flow channel carries vapor from the tobacco in the chamber through the liquid reservoir to the wick where it combines with liquid vapor, the combined vapor then being discharged via a liquid flow-channel through an intake-opening arrangement, which is the part of the device from which the user takes in the vapor from the device. In other words, the intake-opening arrangement may also be referred to as the outlet of the device.
The device of US 2017/071251 A1 has a modular arrangement, with the liquid evaporator forming part of a liquid-evaporator module and the tobacco heater forming part of a tobacco-heater module. The liquid-evaporator module comprises an evaporator-connecting arrangement for connecting to a heater-connecting arrangement of the tobacco-heater module using a bayonet connection.
In an alternative arrangement, the liquid-evaporator module and the tobacco-heater module comprise bayonet connections at both ends, so that the positions of the liquid evaporator module and the tobacco-heater module may be swapped. US 2017/071251 A1 describes a mouthpiece module that may be attached to either the liquid-evaporator module or the tobacco-heater module via the bayonet connection.

Some detailed example embodiments are disclosed herein. However, specific structural and functional details disclosed herein are merely provided for purposes of describing example embodiments. Example embodiments may, however, be embodied in many alternate forms and should not be construed as limited to only the example embodiments set forth herein.
Accordingly, while example embodiments are capable of various modifications and alternative forms, example embodiments thereof are shown by way of example in the drawings and will herein be described in detail. It should be understood, however, that there is no intent to limit example embodiments to the particular forms disclosed, but to the contrary, example embodiments are to cover all modifications, equivalents, and alternatives thereof. Like numbers refer to like elements throughout the description of the figures.
It should be understood that when an element or layer is referred to as being "on," "connected to," "coupled to," "attached to," "adjacent to," or "covering" another element or layer, it may be directly on, connected to, coupled to, attached to, adjacent to or covering the other element or layer or intervening elements or layers may be present. In contrast, when an element is referred to as being "directly on," "directly connected to," or "directly coupled to" another element or layer, there are no intervening elements or layers present. Like numbers refer to like elements throughout the specification.
It should be understood that, although the terms first, second, third, and so forth may be used herein to describe various elements, components, regions, layers or sections, these elements, components, regions, layers, or sections should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer, or section from another region, layer, or section. Therefore, a first element, component, region, layer, or section discussed below could be termed a second element, component, region, layer, or section without departing from the teachings of example embodiments.
Spatially relative terms (for example, "beneath," "below," "lower," "above," "upper," and the like) may be used herein for ease of description to describe one element or feature's relationship to another element or feature as illustrated in the figures. It should be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "below" or "beneath" other elements or features would then be oriented "above" the other elements or features. Therefore, the term "below" may encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
The terminology used herein is for the purpose of describing various example embodiments only and is not intended to be limiting of example embodiments. As used herein, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms "includes," "including," "comprises," and "comprising," when used in this specification, specify the presence of stated features, integers, steps, operations, elements, or components, and so forth, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and so forth, or groups thereof.
When the words "about" and "substantially" are used in this specification in connection with a numerical value, it is intended that the associated numerical value include a tolerance of ±10 percent around the stated numerical value, unless otherwise explicitly defined.
Example embodiments are described herein with reference to cross-sectional illustrations that are schematic illustrations of example embodiments. As such, variations from the shapes of the illustrations are to be expected. Therefore, example embodiments should not be construed as limited to the shapes of regions illustrated herein but are to include deviations in shapes.

As shown in FIGS. 1A-1D, a reservoir 112, first bayonet connector assembly 117, and vaporizer connector assembly 148 may be included in a reservoir assembly 102 of some example embodiments.
As shown in FIGS. 1A-1D, the outer housing 111 of the vapor generator assembly 110 may include an outer housing 113 of the reservoir 112 and an outer housing 131 of the vaporizer assembly 130, where outer housings 113 and 131 collectively define the outer housing 111. In some example embodiments, housings 113 and 131 are separate connectable housings, and in some example embodiments housings 113 and 131 form part of the same housing. The outer housing 113 of the reservoir 112 may at least partially define an interior space 115. The reservoir 112 may be configured to hold a pre-vapor formulation within the interior of the reservoir 112, where the interior may include the interior space 115 at least partially defined by the outer housing 113 of the reservoir 112.

As further shown in FIG. 1B, the fluid port 134 may enable fluid communication between the reservoir 112 and the vaporizer assembly 130. In some example embodiments, the fluid port 134 extends through the outer housing 113 of the reservoir 112, in addition to or instead of extending through the outer housing 131 of the vaporizer assembly 130. In some example embodiments, where housing 113 meets with housing 131 may form part of the same housing, or these may be two separate housings that can be connected together (for example, via complementary connector assemblies 138, 148). In some example embodiments, fluid port 114 may include more than one port (for example, there may be multiple first fluid ports), the fluid port 134 may include more than one port (for example, there may be multiple second fluid ports), or the fluid port 114 and the fluid port 134 may each include more than one port.
The vaporizer assembly 130 may include a heater 136 and a dispensing interface 137. The dispensing interface 137 may be in fluid communication with the fluid port 134 and in fluid communication with the reservoir 112 through at least the fluid port 134, and pre-vapor formulation 174 drawn into the interior space 135 through fluid port 134 may be drawn by the dispensing interface 137 to be in fluid communication with the heater 136. The heater 136 (also referred to herein as a heating element) may heat pre-vapor formulation drawn from the reservoir 112 by the dispensing interface (for example, through the fluid port 134) to generate a vapor.
As further shown in FIGS. 1A-1D, the vapor generator assembly 110 may include an inlet port 132 that extends through the outer housing 131 of the vaporizer assembly 130 and is configured to direct air from an exterior of the vapor generator assembly 110 (for example, an ambient environment) to flow into the vaporizer assembly 130, to flow in fluid communication with the heater 136 within at least a portion of the interior space 135 of the vaporizer assembly 130. As further shown in FIGS. 1A-1D, the vaporizer assembly 130 may include an outlet port 142 extending through the outer housing 131 of the vaporizer assembly 130 and the vapor generator assembly 110 may further include a conduit 140 coupling outlet ports 142, 144 to establish fluid communication between the vaporizer assembly 130 and the exterior of the vapor generator assembly 110 (for example, the ambient environment).
In operation of the e-vaping device 100, air 162 may be drawn into the vaporizer assembly 130 through at least the inlet port 132, vapor generated by the heater 136 may be entrained in the air that is drawn into the vaporizer assembly 130, and a mixture of the air and entrained vapor (simply referred to herein as generated vapor 164) may be drawn from the vaporizer assembly 130 to the exterior of the vapor generator assembly 110 through outlet port 142, conduit 140, and outlet port 144. As shown in FIGS. 1A-1D, the outlet port 142 may extend through the outer housing 131 of the vaporizer assembly 130, the outer housing 113 of the reservoir 112, a vaporizer connector assembly 148, a connector assembly 138, a sub-combination thereof, or a combination thereof.
In some example embodiments, reservoir assembly 102 is configured to enable refilling of the pre-vapor formulation held in reservoir 112. As shown in FIGS. 1C-1D, the fluid port 114 may enable direct fluid communication between the reservoir 112 and an exterior of at least the reservoir 112. Therefore, the reservoir assembly 102 may be configured to enable refilling of the reservoir 112 via introduction of pre-vapor formulation 172 into the reservoir 112 through at least the fluid port 114.
Still referring to FIGS. 1A-1D, the reservoir assembly 102 may include a first bayonet connector assembly 117 that is coupled to a first end 119a of the reservoir 112. The first bayonet connector assembly 117 may include a bayonet plug connector element (also referred to as a male bayonet connector element), a bayonet receptacle connector element (also referred to as a female bayonet connector element), or both a bayonet plug connector element and a bayonet receptacle connector element. Additionally, as shown in FIGS. 1C-1D, the fluid port 114 may extend through the outer housing 113 of the reservoir 112 to an outer surface 119 of the outer housing 113 at the first end 119a of the reservoir 112.
As further shown in FIGS. 1C-1D, the conduit 140 may include a first end 140a and a second end 140b that extend to opposite first and second ends 119a, 119b of the reservoir 112, where the first end 140a of the conduit 140 extends into the first bayonet connector assembly 117 and the second end 140b of the conduit 140 is coupled with the vaporizer assembly 130 (either directly or indirectly via at least a vaporizer connector assembly 148). Accordingly, the conduit 140 may establish fluid communication between the vaporizer assembly 130 and the exterior of the vapor generator assembly 110 through the first bayonet connector assembly 117. As shown, the first end 140a of the conduit 140 may include an opening that is defined as the outlet port 144, and the second end 140b of the conduit 140 may include an opening that is in fluid communication with outlet port 142. In some example embodiments, the first bayonet connector assembly 117 is directly coupled to the first end 140a of the conduit 140. In some example embodiments, where the vapor generator assembly 110 includes the vaporizer connector assembly 148 and the connector assembly 138, the second end 140b of the conduit 140 may be coupled to the vaporizer connector assembly 148, such that the second end 140b of the conduit 140 is configured to couple with the vaporizer assembly 130 through the vaporizer connector assembly 148.
Still referring to FIGS. 1A-1D, the vapor generator assembly 110 may include an outlet assembly 150 (also referred to herein as a mouthpiece, mouthpiece assembly, or the like) that is configured to be detachably coupled 182 to the reservoir 112 via a bayonet interface connection between the reservoir 112 and the outlet assembly 150. As shown, the outlet assembly 150 may include an instance of structural material 152, a conduit 154 extending through the interior of the outlet assembly 150 (for example, through the instance of structural material 152 such that one or more inner surfaces of the instance of structural material 152 may at least partially define the conduit 154) between opposite openings 156, 158, and a second bayonet connector assembly 157. The second bayonet connector assembly 157 may include a bayonet plug connector element (also referred to as a male bayonet connector element), a bayonet receptacle connector element (also referred to as a female bayonet connector), or both a bayonet plug connector element and a bayonet receptacle connector element. As shown in FIGS. 1A-7A, in some example embodiments the structural material 152 of the outlet assembly 150 may define a conical shape, but example embodiments are not limited thereto. For example, as shown in FIGS. 8A-9C, the outlet assembly 150 may include an instance of structural material that defines an outer surface having a cylindrical shape.
As shown in FIGS. 1A-1D, the first and second bayonet connector assemblies 117, 157 may be configured to be detachably coupled with each other to establish a bayonet interface connection between at least the reservoir 112 and the outlet assembly 150, such that the conduit 140 is in fluid communication with an exterior of at least the reservoir 112 through an interior of the outlet assembly (for example, through conduit 154), and the fluid port 114 is isolated from an exterior of at least the reservoir 112 by at least a portion of the outlet assembly 150 to isolate the reservoir 112 from fluid communication with the exterior of at least the reservoir 112 (independently of at least the vaporizer assembly 130). In some example embodiments, the fluid port 114 is configured to be isolated from the exterior of at least the reservoir 112 by at least a portion of the structural material 152 of the outlet assembly 150, at least a portion of the second bayonet connector assembly 157 of the outlet assembly 150, or a combination thereof, based on the outlet assembly 150 being detachably coupled with the reservoir 112 via the bayonet interface connection established via the coupling of the first and second bayonet connector assemblies 117, 157.
Based on the outlet assembly 150 isolating the fluid port 114 based on being detachably coupled with the reservoir 112 via the detachable coupling of the first and second bayonet connector assemblies 117, 157, the transfer of pre-vapor formulation 172 between the reservoir 112 and an exterior of at least the reservoir 112 independently of passing through the vaporizer assembly 130 may be at least partially mitigated. To enable refilling of the pre-vapor formulation 172 in the reservoir 112 via the fluid port 114, the outlet assembly 150 may be detached from the reservoir 112 (via decoupling of the first and second bayonet connector assemblies 117, 157) to expose the fluid port 114 to an exterior of at least the reservoir 112.
In some example embodiments, the first and second bayonet connector assemblies 117, 157 include complementary bayonet connector elements. For example, the first bayonet connector assembly 117 may include a bayonet plug connector element and the second bayonet connector assembly 157 may include a bayonet receptacle connector element that is complementary to the bayonet plug connector element of the first bayonet connector assembly 117, such that at least the first and second bayonet connector assemblies 117, 157 are understood to be complementary with respect to each other and therefore at least the first bayonet connector assembly 117 is configured to detachably couple with the second bayonet connector assembly 157 to establish the bayonet interface connection between the reservoir 112 and the outlet assembly 150 based on the detachably coupling of the complementary bayonet connector elements of the first and second bayonet connector assemblies 117, 157.
In some example embodiments, the vapor generator assembly 110 is configured to provide improved resistance against transfer of pre-vapor formulation 172 from the reservoir 112 to an exterior of at least the reservoir 112 through the fluid port 114 based on the outlet assembly 150 being detachably coupled to at least the reservoir 112 via a bayonet interface connection established by the first bayonet connector assembly 117 coupling with the second bayonet connector assembly 157. In certain example embodiments, the bayonet interface connection may provide improved isolation of the fluid port 114 from the exterior of at least the reservoir 112 in relation to other interface connections, including, without limitation, a threaded interface connection.
Still referring to FIGS 1A-1D, a power supply assembly 120 according to some example embodiments may include a power supply 122.

In some example embodiments, including the example embodiments shown in FIGS. 2A-2B, the first bayonet connector assembly 117 may extend around an outer circumference of an outer surface 119 of the outer housing 113 of the reservoir 112, at the first end 119a of the reservoir 112, such that the first bayonet connector assembly 117 includes one or more bayonet connector elements that face radially inward toward the longitudinal axis 250, and first bayonet connector assembly 117 and the outer surface 119 at least partially define a partial enclosure 217, and the second bayonet connector assembly 157 may extend around an outer surface 152s of the structural material 152 of the outlet assembly 150, such that the second bayonet connector assembly 157 includes one or more bayonet connector elements that face radially outward from the longitudinal axis 250. Examples of first bayonet connector assemblies 117 and second bayonet connector assemblies 157 according to example embodiments are further described below. As shown in FIGS. 2A-2B, when first and second bayonet connector assemblies 117, 157 are coupled together to establish a bayonet interface connection between the reservoir 112 and the outlet assembly 150, the one or more radially-outward facing bayonet connector elements of the second bayonet connector assembly 157 may engage with the one or more complementary and radially-inward facing bayonet connector elements of the first bayonet connector assembly 117, and at least a portion of the second bayonet connector assembly 157 and the structural material 152 of the outlet assembly 150 may occupy the partial enclosure 217.

Still referring to FIGS. 2A-2B, at least the first end 140a of the conduit 140 may extend out of the reservoir 112 and at least partially through the partial enclosure 217 that is at least partially defined by the first bayonet connector assembly 117 and the outer surface 119. As shown in FIGS. 2A-2B, the outlet assembly 150 conduit 154 may include a first portion 254, defined by inner surfaces of the structural material 152 of the outlet assembly 150, that has a first diameter and a first length that substantially corresponds (for example, corresponds within manufacturing tolerances and material tolerances) to a diameter and length of the first end 140a of the conduit 140. Accordingly, as shown in FIGS. 2A-2B, the outlet assembly 150 may enclose the first end 140a of the conduit 140 that extends out of the reservoir 112 and at least partially through the partial enclosure 217 within the first portion 254 of the conduit 154, based on the outlet assembly 150 being detachably coupled to the reservoir 112.

In certain example embodiments, such an enclosure of the first end 140a of the conduit 140 may establish an airtight or substantially airtight seal between the conduit 140 and the outlet assembly 150. In some example embodiments, the conduit 140 is in fluid communication with the exterior of at least the reservoir assembly 102 through the conduit 154 that extends through the interior of the outlet assembly 150. Accordingly, when generated vapor 164 is directed through conduit 140 from a vaporizer assembly 130, the generated vapor 164 may be directed from the conduit 140 to the exterior of the vapor generator assembly 110 through the interior of the outlet assembly 150 (for example, conduit 154).
Still referring to FIGS. 2A-2B, the structural material 152 of the outlet assembly 150 may define a bottom surface 252 of the outlet assembly 150. The outlet assembly 150 may be configured to detachably couple with at least the reservoir 112, based on the first and second bayonet connector assemblies 117, 157 coupling with each other, such that at least a portion of the second bayonet connector assembly 157, the structural material 152 of the outlet assembly 150, or a combination thereof may occupy the partial enclosure 217 and the bottom surface 252 may cover the fluid port 114 extending through the outer surface 119 of the reservoir 112, thereby isolating the reservoir 112 from fluid communication with an exterior of the reservoir assembly 102 independently of the vaporizer assembly 130.
In some example embodiments, including the example embodiments shown in FIGS. 3A-3B, the second bayonet connector assembly 157 may be at least partially located within the interior of the outlet assembly 150 and may extend around an inner surface 152i of the structural material 152 to at least partially define a first portion 254 of the conduit 154 extending through the outlet assembly 150, and the first bayonet connector assembly 117 that is complementary to the second bayonet connector assembly 157 may extend around an outer surface 140as of the first end 140a of the conduit 140, such that the first bayonet connector assembly 117 includes one or more bayonet connector elements that face radially outward from the longitudinal axis 250 and such that the first end 140a of the conduit 140 extends through the first bayonet connector assembly 117.

In some example embodiments, each bayonet connector assembly of the first and second bayonet connector assemblies 117, 157 may include multiple bayonet connector sub-assemblies that each include one or more bayonet connector elements. As a result, detachably coupling the outlet assembly 150 with the reservoir 112 may include detachably coupling multiple bayonet connector sub-assemblies of the first bayonet connector assembly 117 with separate, respective complementary bayonet connector sub-assemblies of the second bayonet connector assembly 157 to establish multiple bayonet interface connections between the outlet assembly 150 and the reservoir 112. In some example embodiments, each bayonet connector assembly of the first and second bayonet connector assemblies 117, 157 may include multiple bayonet connector sub-assemblies that each include one or more bayonet connector elements, based on a combination of the embodiments of the bayonet connector assemblies shown in FIGS. 2A-2B and FIGS. 3A-3B.

As shown in FIGS. 8A-9C, the outlet assembly 150 may include an instance of structural material 152 that defines a cylindrical outer surface of at least a portion of the outlet assembly, and at least a portion of the housing 111 of the vapor generator assembly 110 (for example, at least a portion of the housing 113 of the reservoir 112) may be transparent or translucent to visible light.
As shown in at least FIGS. 8E-8G, detachably coupling the first and second bayonet connector assemblies 117, 157 of the reservoir 112 and outlet assembly 150, respectively, may include inserting 790 at least the second bayonet connector assembly 157 into the partial enclosure 217, such that one or more coaxial channels 708 of the second bayonet connector assembly 157 are aligned with the one or more plug structures 704 of the first bayonet connector assembly 117 and the inserting 790 results in the one or more plug structures 704 being received into circumferential groove 706 via the one or more coaxial channels 708.
As shown in FIGS. 8A-9C, in some example embodiments the first bayonet connector assembly 117 includes at least two plug structures 704 extending radially inward from opposite inner sides of a base structure 702, and the second bayonet connector assembly 157 includes at least two coaxial channels 708 extending along opposite outer sides of the second bayonet connector assembly to the circumferential groove 706, but example embodiments are not limited thereto. For example, in some embodiments, the first bayonet connector assembly 117 may include only one plug structure 704, or the second bayonet connector assembly 157 may include only one coaxial channel 708, or the first bayonet connector assembly 117 may include only one plug structure 704 and the second bayonet connector assembly 157 may include only one coaxial channel 708. In another example, the first bayonet connector assembly 117 may include two or more plug structures 704, or the second bayonet connector assembly 157 may include two or more coaxial channels 708, or the first bayonet connector assembly 117 may include two or more plug structures 704 and the second bayonet connector assembly 157 may include two or more coaxial channels 708. The detachably coupling of the first and second bayonet connector assemblies 117, 157 may further include rotating 792 the outlet assembly 150 in relation to the reservoir 112 around the longitudinal axis of the vapor generator assembly 110, so that the one or more plug structures 704 of the first bayonet connector assembly 117 move through circumferential groove 706 to become mis-aligned with the one or more coaxial channels 708 to complete the bayonet interface connection between the reservoir 112 and the outlet assembly 150.
As shown in FIGS. 8A-9C, the first bayonet connector assembly 117 may include a base structure 702 that forms an upper lip structure that extends around a top edge of the one or more inner sides of the base structure 702, and the one or more plug structures 704 may extend from the one or more inner sides of the base structure 702 and beyond the one or more edges of the upper lip structure. As further shown in FIGS. 8A-8G, the one or more plug structures 704 may extend through a separate structure that is located within the one or more spaces bounded by the one or more inner sides of the base structure 702 and the upper lip structure of the base structure 702.
Detaching the outlet assembly 150 from the reservoir 112 may include performing the reverse of the above process, where the outlet assembly 150 is rotated 792 in relation to the reservoir 112 to cause the one or more plug structures 704 to move through circumferential groove 706 to be aligned with the one or more coaxial channels 708 and then removing the outlet assembly 150 from the partial enclosure 217 such that the plug structure 704 moves through the aligned coaxial channel 708 to disengage from the second bayonet connector assembly 157 via the coaxial channel 708.
It will be understood that the rotation 792 shown in FIG. 8G is not limited to the direction shown in FIG. 8G. For example, the rotation 792 could be clockwise, counter-clockwise, or both clockwise and counter-clockwise. In some example embodiments, the rotation 792 to detachably couple the outlet assembly 150 to the reservoir 112 is in the same direction as the rotation 792 to detach the outlet assembly 150 from the reservoir 112. In some example embodiments, the rotation 792 to detachably couple the outlet assembly 150 to the reservoir 112 is in an opposite direction as the rotation 792 to detach the outlet assembly 150 from the reservoir 112.
At least one of the first bayonet connector assembly 117 and the second bayonet connector assembly 157 may be configured to generate an audible signal (for example, a "click" sound) based on interaction between elements of the first and second bayonet connector assemblies 117, 157 as a result of the bayonet interface connection between the reservoir 112 and the outlet assembly 150 being established or terminated via coupling or decoupling of the first and second bayonet connector assemblies 117, 157, respectively. In some example embodiments, at least one of the first bayonet connector assembly 117 and the second bayonet connector assembly 157 may include a structure that is configured to arrest rotation 792 to detachably couple the outlet assembly 150 the reservoir 112, in order to prevent re-alignment of the one or more coaxial channels 708 of the second bayonet connector assembly 157 with the one or more plug structures 704 of the first bayonet connector assembly 117, thereby preventing inadvertent detachment of the outlet assembly 150 from the reservoir 112 when attempting to detachably couple the outlet assembly 150 to the reservoir 112. In some example embodiments, such a structure may be absent from both the first and second bayonet connector assemblies 117, 157, such that the rotation 792 of the rotation of the outlet assembly 150 when the one or more plug structures 704 are received into the circumferential groove 706 is unrestricted.
While a number of example embodiments have been disclosed herein, it should be understood that other variations may be possible. Such variations are not to be regarded as a departure from the scope of the present disclosure, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
